Problem Analysis

Two cyclists start from two different cities and travel towards each other. After 5 hours, the distance between them is 190 km. One cyclist is traveling at a speed of 14 km/h, while the other is traveling at a speed of 17 km/h. We need to find the distance between the cities.

Solution

Let's assume that the distance between the two cities is x km.

The first cyclist is traveling at a speed of 14 km/h, so in 5 hours, they would have covered a distance of 14 km/h * 5 h = 70 km.

The second cyclist is traveling at a speed of 17 km/h, so in 5 hours, they would have covered a distance of 17 km/h * 5 h = 85 km.

The total distance covered by both cyclists is the sum of the distances covered by each cyclist: 70 km + 85 km = 155 km.

Since the distance between the two cyclists after 5 hours is 190 km, we can set up the following equation:

x - 155 km = 190 km

Simplifying the equation, we get:

x = 190 km + 155 km = 345 km

Therefore, the distance between the two cities is 345 km.

Answer

The distance between the two cities is 345 km.
